Arina Ielchiieva commented on CALCITE-1584:
-------------------------------------------
Thanks for explaining. Julian regarding Drill problem so you are saying there
is nothing we can do here unless from Drill side we disable ProjectRemoveRule?
One more question here: before Vladimir changes columns names were taken into
account in isTrivial method, I am not quite clear why it was decided to remove
this check?
> ProjectRemoveRule loses field names
